What is it?

Routup is a minimalistic, runtime-agnostic HTTP routing framework built on srvx and Web Standards. Handlers receive an event object (IRoutupEvent) and return values that are automatically converted to Response objects.

It runs on Node.js, Bun, Deno, Cloudflare Workers, and any runtime that supports the Web API.

Quick Example

import { Router, defineCoreHandler, serve } from 'routup';

const router = new Router();

router.get('/', defineCoreHandler((event) => {
    return { message: 'Hello, World!' };
}));

router.get('/users/:id', defineCoreHandler((event) => {
    return { id: event.params.id };
}));

serve(router, { port: 3000 });
